Transcutaneous Auricular Vagus Nerve Stimulation Added to Physiotherapy for Adhesive Capsulitis
This randomized, sham-controlled study will evaluate whether transcutaneous auricular vagus nerve stimulation (taVNS), when added to standard physiotherapy, improves pain, shoulder function, range of motion, and quality of life in adults with adhesive capsulitis. A total of 40 participants aged 18 to 65 years will be randomly assigned to one of two groups. Both groups will receive 15 sessions of standard physiotherapy over 3 weeks. In addition, one group will receive active taVNS for 30 minutes per day, while the other group will receive sham stimulation for the same duration and frequency. Assessments will be performed before treatment and after the 15th treatment session using pain, shoulder disability, quality-of-life, and shoulder range-of-motion measurements.
